explain the acidity and basicity with increasing or decreasing order of ph
Answers
As the pH diminishes, the acidity is greater. When the pH increases, the acidity is lesser. Thus, the basicity increases.
Answer:
As the pH diminishes, the acidity is greater. When the pH increases, the acidity is lesser. Thus, the basicity increases
Explanation:
Acidity is the extent to which a substance will donate a proton/hydrogen ion. Substances with high acidity will donate a proton easily while substances with low acidity will rarely donate protons and in presence of more acidic substances, accept a proton. For example, hydrochloric acid will easily donate protons to water like so (water acts as a base in this case):
HCl (aq) + H2O (l) → Cl- (aq) + H3O+ (aq)
Basicity is the extent to which a substance will accept a proton/hydrogen ion. An example of a strongly basic substance is sodium hydroxide, which will accept a proton from water (or any other ‘acid’) like so:
NaOH (s) + H+ (l) → Na+ (aq) + OH- (aq)
Alternatively, this can be written as:
NaOH (s) → Na+ (aq) + OH- (aq)
Alternatively, the Lewis definition defines acids as substances which accept an electron pair and bases as substances which donate an electron pair.
